provides the flexibility to transport the Mitre 
Saw to other work areas.
Note: 

Ensure the mounting surface is not 

warped as an uneven surface can cause
binding and inaccurate cutting.

RELEASING THE HEAD LOCKING PIN
The head locking pin is used to hold the 
cutting head down when transporting
or storing the Mitre Saw. The Mitre Saw 
must not be used when it is in lockdown 
position.
1. To release the cutting head push down 
on the operating handle and pull the
head locking pin. Rotate the pin a quarter 
to secure it in the released position (Fig. 2).
2. Gently raise the cutting head.

ADJUSTING THE MITRE ANGLE

The mitre table lock knob is used to lock 
the rotating mitre table at the required 
mitre angle.
The Mitre Saw cuts from 0° to 45° both left 
and right. The rotating mitre table features 
positive stops at 0°, 15°, 22.5°, 30° and 45° 
for quick and accurate setting of common 
mitre angles. The mitre angle indicator 
shows what mitre angle the Mitre Saw is 
set to (Fig. 4).

To adjust the mitre angle proceed as 
follows:
1. Rotate the mitre table lock to unlock it 
(Fig. 5).
2. You can now set the desired mitre angle 
by rotating the mitre table to the left or 
right, using the mitre angle indicator to 
select the required mitre angle.
3. The mitre table will stop at each 
common cutting angle.

Warning: 

Ensure the mitre table lock 

knob is tight before making a cut. If 
it is not secured, the table may move 
during operation and cause serious
personal injury.
